NOS 105 Group
The New Old Stock 105 “9 speed generation” group is our favorite group because of it’s beauty, price and quality.
They were still made in Japan, unlike most much more expensive, lower quality and uglier offerings available new today.
The rear hub is still a real tradition “loose ball” cup and cone hub. Easy to service and grease and replace the bearing just like any vintage hub.
Notice the elegant “small barrel,” the chrome lock nuts and alloy spacers.
The cassette body is made from steel so you can use any cassette you like. It has the traditional spacing used from 8 speed through 10 speed. So any 8-10 speed cassette will fit (*excluding Campagnolo). 7 speed cassettes will fit with the addition of a 4 mm spacer.
The body is alloy and the cage is chrome plated steel. They work well with road rings and are the best front derailleurs we’ve found for use with compact doubles.
They all have a 28.6 clamp size for standard, or single over sized tube sets (and are compatible with all bikes we make).
The rear derailleurs only come in the short cage. These are best for very compact cassettes such as 11-25.
Matching the group:
We like matching up this Ultegra group with a Son dynamo front hub, Sun Xcd crank set with T.A. chain rings mounted with Velo Orange 50.4 hardware. Shimano dura ace 9 or 10 speed down tube shifters KMC Ultra light chain and Ultegra cassettes.
